11.Why is it that aluminium which is more reactive than iron dies not corrode like iron?

12. Why are carbonate and sulphide are usually converted into oxides during the process of extraction. Solution1. When the surface of some metals exposed to air for a long time acquires a dull appearance because it form thin layer oxide , carbonate and oxide on their surface

2. Sodium is kept immersed in kerosene because it reacts so vigorously that they catch fire when kept in the open. Hence to protect them and to prevent accidental fires, they are kept immersed in kerosene.

3. Salt is composed of positive sodium ions and negative chloride ions. In solid these ions are arranged with great force of attraction and unable to move. So in melted state its ions become free to move and conduct electricity.

4. Ionic compounds have high melting and boiling points because a considerable amount of energy is required to break the strong inter-ionic attraction. Ionic compounds form crystals.[ These crystals are basically just great big blocks of positive and negative charges all stuck together. ]

5. An iron grill is painted frequently to prevent it from rusting. Iron when exposed to moist air for a long time acquires a coating of a brown flaky substance called rust.

6. Aluminium was discovered by Oersted in 1825. It is the most abundant metal in the earth crust. Aluminium is a reactive metal and so does not occur free in nature Aluminium oxide due to its great affinity for oxygen is a very stable compound. It is not reduced easily by common reducing agents like carbon, carbon monoxide or hydrogen.. Hence, electrolytic reduction was chosen as the method for reducing alumina.

7. Aluminum is a highly reactive metal, still it is used to make utensil for cooking because it is conductors of heat, have high melting points malleable , ductile and less corrosive

8 Platinum, gold and silver are used to make jewellery because of their malleability and ductility.

9. Sodium, potassium and lithium are highly reactive metals so they are stored under oil because they catch fire if kept in the open or react violently if kept in cold water .

10. Zinc metal can displace copper from copper sulphate solution but copper cannot displace zinc from zinc sulphate solution as zinc is more reactive than copper.

11. Aluminum which is more reactive than iron does not corrode like iron because as aluminum react with air and moisture form layer of aluminum oxide that seals out oxygen and no more oxidation will take place and aluminium corrode slowly than iron.

12. Carbonate and sulphide ores are are usually converted into oxides during the process of extraction. because their direct reduction to obtain metals is not possible so It is easier to obtain a metal from its oxide as compared to its sulphides and carbonates

There shall be only one paper in this category. All questions will be Multiple Choice Questions (MCQs) each carrying one mark with four alternatives out of which one answer will be correct.

No. of MCQs–150; Duration of Examination: one-and-a-half hours.

Structure and Content:

(i) Child Development & Pedagogy (compulsory) 30 MCQs 30 Marks

(ii) Language I (Hindi)(Compulsory) 30 MCQs 30 Marks

(iii) Language II(English) (Compulsory) 30 MCQs 30 Marks

(iv) Subject specific 60 MCQs 60 Marks

NATURE AND STANDARD OF QUESTIONS:

• The test items on Child Development and Pedagogy will focus on educational psychology of teaching and learning, relevant to the age group of 14-17 years. They will focus on understanding the characteristics, needs and psychology of diverse learners, interaction with learners and the attributes and qualities of a good facilitator of learning.

• The test items for language I (Hindi) will focus on the proficiency related to the medium of instruction relevant to the age group of 14-17 years.

• The Language II (English) will focus on the elements of language, communication and comprehension abilities relevant to the age group of 14-17 years

• The questions in the test will be based on the topics of the prescribed syllabus of the Board of School Education BIHAR for classes IX-XII but their difficulty standard as well linkages could be upto the Post-Graduate level.

Metals are solids at room temperature with the exception of mercury and gallium, which are liquids at room temperature. Gallium and Caesium melt below 30c . So if room temperature is around 30c, they may also be in liquid state

Metals are hard but not brittle, except zinc at room temperature.

Metals, in their pure state, have a shining surface. This property is called metallic luster e.g., gold, silver and copper

Metals can be beaten into thin sheets known as foils. This property is called malleability. Gold and silver are the most malleable metals.For full study materialclick me
